Decision Support System for Proposed Physical Development of Bantul Building Using Case-Based Reasoning

Abstract

In accordance with Regulation number 1 the year 1994 concerning the general spatial plan, the development must be optimally utilized without ignoring the principle of balance and sustainability. Development programs implemented by the Government of Bantul (for the rest of the abstract defines as Bantul), specifically the physical construction of the building, or in other words the infrastructure is currently progressing incredibly fast. It is marked with the number of facilities and public services buildings in the Bantul such as government buildings, educational and health facilities, etc. The process of physical building assessment submitted by the regional work units (Satuan Kerja Perangkat Daerah/SKPD). It requires good planning since it involves massive costs and also complies with general spatial planning of Bantul. This research aimed to establish a system of decision making to assess a proposal of the physical development building by using case-based reasoning (CBR). The assessment process is done by entering values on the elements of assessment and also to determine the priority rating for each type of building. The algorithm used is k-Nearest Neighbor with a similarity function by using the Normalized Euclidean Distance. The results show that recommendations follow-on from physical development proposal assessment decision depends on the recommendation of previous cases buildings that ranked first in a list of cases with the results of its smallest Euclidean. Leaders as decision-makers can make decisions by following recommendations issued by the system, but leaders can also determine the outcome of their decisions without following system recommendations.
